Reverse Osmosis System without pump

Reverse Osmosis is a process where water is demineralised using a semi permeable membrane at high pressure. Your normal filtration units will only reduce certain contaminants such as silt, rust, chlorine and bacteria (up to 96%). Reverse Osmosis machines will purify your water up to 99.9% or 0.001 microns, thus removing other dissolved contaminants like Colloid, lead, mercury, germs and other metals.

Stage 1 : Polypropylene Cartridge – 5 Micron Superfine Filter – Removes solid particles & impurities i.e. silt & rust.

Stage 2 : Granular Activated Carbon (UDF) Filter – Absorbs odours, chemicals & chlorine.

Stage 3 : Carbon Block Filter (CTO) – removes additional chlorine & water decolourants.

Stage 4 : Reverse Osmoses Membrane – Removes up to 0.0001 microns colloid, metals, germs & bacteria.

Stage 5 : Post Carbon Filter (T33) – improves water taste.

Faucet and all necessary installation fittings are included.

Operating Pressure: 50 - 100 psi (3.5 to 6.5 bar)

If your water pressure is above 6 BAR you will need a pressure reducing valve to keep your pressure within the operating pressure limits.

If your water pressure is below 3.5 BAR the RO will not produce any water, in this case you need the RO with a booster pump, if unsure you should rather buy the RO with the pump.

This unit produces up to 50 Gallons (189 litres) every 24 hours where water pressure is at least 5 BAR.

10L Storage tank.

This unit does not have a pump and does not use electricity.

We recommend that a plumber install the unit as a pressure reducing valve may be required.
